Uber already made that decision right after the accident. Today, it notified the California Dept. of Motor Vehicles (DMV) that it will not renew its permit to operate autonomous vehicles in the state. The permit will expire this Saturday.

DMV said Uber would need to reapply once information is available from the Arizona crash investigation. The agency might also require Uber officials to have an in-person meeting.

"I'm absolutely worried about public reaction," said Tim Wong, a spokesman for NVIDIA's automotive sector. At the same time, he affirmed the company's commitment to save lives and to provide mobility to adults who, in later years, might be incapable of driving themselves.

The many companies working on autonomous vehicle technology, such as the San Francisco start-up Ouster, hope this chain reaction to the Arizona accident doesn't create a setback for a very fast-moving and highly competitive sector.

"This was bound to happen at some point. It's unfortunate it happened so quickly," said Raffi Madrosian, vice president of Ouster. "I hope we kind of move past this and still enable the industry to the research it needs to get vehicles on the road."

Dr. William Riggs, a management professor at the University of San Francisco, focuses on transportation and technology. He says more regulation may be needed, but to save lives, testing must continue. The longer it takes to attain truly self-driving vehicles, the more injuries or deaths could occur.
